Facile synthesis of ultrathin worm-like Au nanowires for highly active SERS substrates

Abstract

Ultrathin worm-like Au nanowires were facilely synthesized and used for the fabrication of porous Au films as highly active SERS substrates.

l-Arginine-assisted electrochemical fabrication of hierarchical gold dendrites with improved electrocatalytic activity

“…However, the peak intensity ratio of the Au (111) planes relative to the Au (200) planes is 2.35 for dendritic Au nanostructures, which is larger than that of Au nanoparticles (1.96), while it is close to Au dendrites in the literature [31]. These observations strongly show the preferential growth along the (111) directions of dendritic Au nanostructures [41][42][43].…”

In situ polydopamine-assisted deposition of silver nanoparticles on a two dimensional support as an inexpensive and highly efficient SERS substrate

“…5D(c)), which is believed to be from the strong coupling of closely-packed AgNPs. 43,44 However, in the case of using AgNO 3 solution with the concentration at 25 mg mL À1 , the resultant AgNPs in the substrate were uneven, some are even fused together (pointed by arrow in Fig. 5D).…”

One Dimensional AuAg Nanostructures as Anodic Catalysts in the Ethylene Glycol Oxidation

“…We propose that the 1D nanomaterials were formed via a two-step process involving the orientated attachment of Au and Ag seeds during the aging period to form ultrathin NWs [58]. Following the dilution step, the excess seeds in dispersion underwent a controlled fusion with the ultrathin NWs to form the resulting thicker NWs [59,60]. Therefore, keeping the reaction mixture at a fixed temperature served to accelerate the nucleation and growth processes of the template NWs during aging, resulting in fewer excess seeds in solution [61].…”
